Igcse Model Questions Vol1 2022 Physics Question 10
Practice objective / multiple choice question 10 from the 2022 Igcse Model Questions Vol1 Physics examination.
Two identical loudspeakers are placed \(1.0\ \text{m}\) apart. A point P lies on the perpendicular bisector of the line joining the speakers at a distance \(d\) from the midpoint. The speakers emit sound of equal power and are in phase, so the intensities at P add constructively. At a point Q that is \(2.0\ \text{m}\) directly in front of one speaker, the intensity is measured to be \(I_Q\). Find the distance \(d\) (in metres, to two decimal places) at which the resultant intensity at P is exactly twice \(I_Q\).
